如何将 2 个网络摄像头连接到一台 PC?
如何将两个网络摄像头连接到一台电脑?我需要同时从两个网络摄像头输入中抓取帧。我应该使用什么软件?是否需要任何额外的硬件?我更喜欢使用 USB 连接相机,因为大多数计算机都有多个此类端口。另请建议适用于 Linux 的解决方案。我使用的是 Ubuntu 9.04。
How do I connect two webcams to a PC? I need to grab the frames from the two webcam inputs simultaneously. What software should I use and is there any extra hardware that I will need? I prefer connecting the cameras using USB as most computers have several of these ports. Also please suggest solutions that will work in Linux. I'm using Ubuntu 9.04.

只需将它们插入即可。内核将加载驱动程序并创建两个视频设备,您可以在其中抓取帧。它们不会 100% 同步,因此要准备好时不时地丢帧。
Just plug them in. The kernel will load the driver and create two video devices where you can grab the frames. They won't be in sync 100% so be ready to drop frames every now and then.
插入第一个,然后插入第二个。每个都有自己的可用于捕获的
/dev/videoX
节点。不确定是否有任何预先打包的捕获软件;您也许可以在 ZoneMinder 中找到一些想法。Plug the first one in, then plug the second one in. Each will have its own
/dev/videoX
node that can be used for capture. Not sure if there's any prepackaged software for capture though; you might be able to find some ideas in ZoneMinder.
